Research interests:

Storm track dynamics and variability:
Observations of the interannual and
decadal variations of the Northern Hemisphere storm tracks. The
relationship between the interannual
variations of the jet and storm track strength in the Pacific.

Mid latitude eddy life cycle dynamics.
The effects ofbasic state wave geometry
on the life cycles (LC1 vs LC2), and
possible consequences for larger scale circulation-strom track structure and
variability, the response of midlatitudes to El Nino.
